Procedure
A mixture of 12.25 g of the product obtained in Step 2, 1 g of para-toluenesulphonic acid and 200 ml of toluene is heated at reflux for 5 hours. After returning to ambient temperature, washing the toluene solution with a 0.1N solution of sodium hydroxide and then with water, drying over magnesium sulphate and concentration, the expected product is obtained.
